The disgraced ex-headteacher who had regular sex with his PA in his "sex dungeon" office was able to get away with his deplorable behaviour due to his "controlling and autocratic" nature.

Sawtry Village College bursar Lisa Killner heard former principal James Stewart, 72, laughing in his office with his married PA Christine Laxton, along with clear sounds of a “sexual nature, rhythmic moaning and banging”.

Stewart would also be heard serenading Mrs Laxton on the electric piano he kept in his office and they would often be seen in a disheveled state with red wine stains around their mouths.

As well as specially adapting part of his office into a squalid and seedy sex dungeon, Stewart splurged more than £100,000 of school money on London hotels, skiing holidays, gadgets, fish and wine to name a few indulgences.

Various members of staff saw "troubling behaviour" but given Stewart's close relationship with Mr Leighton, they felt little could be done. It was hoped Stewart's impending retirement would lead to positive changes.

Previous vice principal Sarah Wilson said she had “increasing concerns of his stark management and behaviour” while responsible financial officer John Kelly would sign off any expense claims because "he would do what he was told to do".

'Racist, sexist and fattist bully'

Labelled a "racist, sexist and fattist bully" by staff, Stewart would do everything in his power to undermine those who questioned him. He even boasted his management style was "to divide and conquer".

One time Stewart claimed he had to go to a meeting. He was later seen on Channel 4 by Miss Killner at Newmarket Racecourse's enclosure ring.

A number of unsuitable items were found

Staff knew it was best to approach him after lunch because he would be “most amenable”. If not drunk he would be more helpful.

His deputy, 64-year-old Alan Stevens, who was also sentenced for two frauds, was described as being "in awe" of the "controlling and autocratic" Stewart by Judge Stuart Bridge.

Described by a former pupil as "selfless and giving", it was said in court Stevens, who feels he was “a naive idiot and was duped”, also "didn't have the courage to challenge the dominance of Stewart and just kept his head down".

As he sent him to prison, Judge Bridge told Stewart: “Being bullying, overbearing and superior gave you the power you need which you then sought to exploit.”
